Be it known that I, FRANCIS T. JOHNSON, a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented a certain new and useful Improvement in Clutch and Brake Mechanism, of which the following is a specification, being a divisional application of N 0. 32,525, Francis T: Johnson, washingmachine, filed'June 7, 1915.

My invention relates to improvements in clutch and brake mechanism,.such as are particularly adapted for use in connection with washing machines and the like.

I have illustrated my invention as applied to washing machines wherein the tub is of the oscillatory type, though of course it from the oscillating drum. would be quite obvious that the mechanism B is a carriage connected to the part B mi ht be employed in other connections, by the pins B, and B a controlling member no object of my invention is to provide a pro ecting outwardly therefrom through'the clutch which can be used to efi'ect disconaperture 35 in the frame A.

is a control rod vertically disposed mounted in bearings C C on the front side of the fraine'A. It has a controlling handle (P. This handle has a' stop (imp nging member C adapted to engage the huttonC on the bearing C is a lever engaging the part B so that a rotation of the member C will cause the quadrant tomove back and forth to move the clutch into and out of engagement with the oscillating drum.

D is a cam mounted on the shaft (1 adjucent its lower end. This cam is adopted to engage the brake block D which block is slidable 0n the pins 13*, toward and from the lower side wall of the tub A adjacent its periphery. 'l 16 position of the cam and the lever C is such that when the rod is rotated to throw tire position, it will also disengage the brake, when the rod is rotated to throw the clutch brake will be caused to engage the lower wall of the tub and bring it to rest.

It will be evident that while I have shown driving member and an oscillatingidriven clutch.

Another object is to provide the combina tion between a clutch for driving an oscil lating tub and a brake for arresting its movement, in such way that whenever the at whatever position it may at that time be occupying.

Other objects will appear from time-to time in the specification.

It is illustrated in the accompanying drawings, wherein Figure l is a front elevation with parts in section and ports broken away of a washing machine tub showing my drive applied. Fig. 2 is a side elevation in part section of a part of the washing machine on an enlarged scale, showing an assembly of clutch, brake, driving mechanism and control. Fig. 3 is a section along line of ig. 2. Fig. at is a section along line 4% of Fig. 2. Fig. 5 is a section along line 55 of Fig. 2.

Like parts are indicated by like characters in all the figures.

A is an end frame adopted to support a. washingmachine or other similar mechanism. it carries the two dri ing wheels A, A, and an oscillating segment A This oscillating segment is driven by the rotation of the gears A A operating through a link chain A wound partially around the oscilmany changes might be made'hoth in size, shape and arrangement of parts without departing materially from the spirit of my invention, and I wish, therefore, that my drawiugsmay be regarded as in a sense diagrammatic.

are as tollmvst-Jl'ith the parts as shown, the tub or other part which is to be driven or oscillated, is driven when the lever is moved so that it engages the oscillating drum, and is found in the position shown in dotted lines. At this point the brake will be out of engagement with the tub, and the oscillation of the drum caused hv the rotation of the two driving gears in unison delineated. which drive the chain or loop,

and thus the drum will cause the tub to osplied by the brake \Vlll depend upon the s for throwing it pressure exerted by the operator in rotating the control shaffi If he merely rotates enough to just disengage the clutch arm, the brake will be hardly it any applied, but an ordinary full movement will of course apply the brake with full. strength and bring the tab to rest permitting the oscillating drum to continue its oscillation without aiiecting the tub holding the tub in post tion.

I claim:

1. A power transmission comprising a shaft, a clutch arm mounted for rotation in plane containing the axis of the shaft, but held against rotation about the shaft, a drum and means for rotating it, and means for thrusting said arm in engagement with the drum to complete the driving connection, said means comprising a guide plate always in engagement with the h: 'r inde pendent of its position,

.i d means for mov ing the plate to and from the drum.

2. A clutch comprising a slotted driving drum, a driven member and a clutch arm pivoted thereon and means for rotating said arm to shift it out of and thrust it into the slot in thegdrum, said means comprising a. pair of curved fingers in slidable rotatable relation with the end of the clutch arm, said fingers being substantially concentric with the driving drum.

3. The combination with a rotary wash ing machine tub of a rotary driving memher, a clutch arm carried thereby, and means v into and out of operative engagement with the rotary member, a brake member adapted to engage tub, and means responsive to the clutch operating means vi'or throwing the brake member from into engagement, with the tub when the clutch arm is out of engagement with the driving, means.

The combination with a shaft mounted for oscillation of a clutch. arm carried there by held-againstrotation thereabout and free to swing in a radial plane with respect to the shaft, a driving segment and means for oscillating it, its periphery being at one point slotted to engage the arm. and means -for swinging said arm into and out of engagement with said slot to connect and disconnect the driving and the driven part:

5. The combination with a shaft mounted for rotation of a clutch arm carried thereby held against rotation thereabout and free to swing; in a radial plane with respect o the shaft. a drir'ng segment and means for rorating; it its periphery being" at one point slotted to. engage the arm. and means for swinging said arm into and out of engagement with said slot to connect and disconnect the driving and the driven part, a driven member carried by the shaft a brake adapted to he thrust against the driven member, and a connection between the brake and the clutch lever swinging mechanism to cause engagement of the brake when the lever is swung out of the operative position.

(3 A. driving and brake mechanism for washing machine tubs and the like, comprising a shaft upon which the tub ismoui'ited a elitch arm mounted for rotation on the shaft in a radial plane and held against rotation about the shal't. a rotating slotted men'ilier and means for (ll'lYillfZ it, a control shaft and means responsive to its manipulation for throwing the clutch arm into and out ol engagement with the slot, and for throwing the brake out of and into en jage ment with the tub.

T. A power transmission device comprising longitudinally slotted shatt, a clutch arm pivoted in such slot and hold by pivot connmttion against rotation about the oi the shaft, a clutch drum mounted for rotation on the suaft and slotted, means for thrusting: the clutch arm into and drawing it out of engagement with the slot in the drum, and comprising a segment concentric with the druim means for moving it along a line parallel with the axis of the shaft, the end of the clutch arm being slotted to engage the segi'nent.

In testimony whereof, I atlix my signaturn in the presence of two witnesses this 14th (lay of February, 1916.
